AIM: To observe and analyze the curative effect of YAG laser combined with routine medicine in treating delayed anterior fibrinous membrane after intraocular lens implantation.

METHODS: A case control study was adopted and 62 cases(62 eyes)were randomly divided into treatment group(31 cases)and control group(31 cases).All the patients had delayed anterior uveitis after intraocular lens(IOL)implantation with IOL anterior fibrinous membrane reached the grade 3 or above. YAG laser combined with routine medicine were used intreatment group, while conventional medical treatment were performed in control group. All the patients were followed-up for 2-3 months.

RESULTS: Visual acuity were improved at different levels, anterior fibrinous membrane absorbed and inflammation subsided after treatment in both groups., there were no significant differences of visual acuity and intraocular pressure in both two groups between pre-operation and post- operation(all P>0.05). The cure time of the treatment group(14.6±2.3d)was significantly shorter than that of the control group(20.4±3.4d)(P<0.01). No serious complication was found in both two groups postoperatively.

CONCLUSION: The YAG laser combined with routine medicine has a satisfactory curative effect in treating delayed anterior fibrinous membrane after intraocular lens implantation.
